Thunderstorms observed by radio astronomy Explorer 1 over regions of low man made noise

Radio Astronomy Explorer (RAE) I observations of thunderstorms over regions of low man-made noise levels are analyzed to assess the satellite's capability for noise source differentiation. The investigation of storms over Australia indicates that RAE can resolve noise generation due to thunderstorms from the general noise background over areas of low man-made noise activity. Noise temperatures observed by RAE over stormy regions are on the average 10DB higher than noise temperatures over the same regions in the absence of thunderstorms. In order to determine the extent of noise contamination due to distant transmitters comprehensive three dimensional computer ray tracings were generated. The results indicate that generally, distant transmitters contribute negligibly to the total noise power, being 30DB or more below contributions arriving from an area immediately below the satellite

Novel solid-state emissive polymers and polymeric blends from a T-Shaped benzodifuran scaffold: A comparative study

Two novel polyimines were synthesized from a benzodifuran based diamino monomer and two dialdehydes bearing bulky groups and a flexible spacer. The polymers display tuned luminescence performance according to the presence of half-salen groups. The effect of the intramolecular bond on the emission properties were examined. Two model compounds, replicating the same emissive Schiff base cores, were synthetized. From the models, dye-doped blends in the fluorophore/matrix ratio, resembling the polymers, were produced. Amorphous thin films of the covalent polymers and the polymeric blends were obtained by spin-coating technique. The Photoluminescent (PL) response of the different macromolecular systems were qualitatively and quantitatively examined and compared

A Closer Look at the Test of Personal Intelligence Presentation

Personal intelligence is the capacity to reason about personality and personality-related information. To understand more about the structure of the mental abilities involved in personal intelligence, we fit several factor models to an ability based test of personal intelligence. A two-factor oblique simple structure model fit the data well. The findings inform us about the nature of abilities people use to understand personality in themselves and others

A closer look at the Test of Personal Intelligence (TOPI)

Personal intelligence involves the capacity to reason about personality and personality-related information. Studying ability-based measures of personal intelligence creates a virtuous cycle of better measurement and better theoretical understanding. In Study 1 (N = 10,318), we conduct an item-level analysis of the Test of Personal Intelligence (TOPI) to explore people\u27s problem-solving abilities in the area. Personal intelligence divided into a Consistency-Congruency factor that concerned understanding traits and their associated behaviors, and a Dynamic-Analytic factor that involved understanding personality processes and goals. The finding cross-validated in Study 2 (N = 8,459). In Study 3 (N = 384), we examined correlates of the two factors. Understanding the abilities involved in personal intelligence may help us to educate people about how to better solve problems about personality

Technical Report for “When People Estimate their Personal Intelligence Who Is Overconfident? Who is Accurate?”

The Technical Supplement includes additional information about the article “Who Believes they are High in Personal Intelligence.” The Supplement is organized such that material follows the organization of the article, with the exception that group-wise analyses—i.e., analyses based on median splits of the archival samples on the Test of Personal Intelligence and Self-Estimated Personal Intelligence, are in their own Appendix owing to the considerable length of that material

Employees high in personal intelligence differ in workplace perceptions and behavior from their colleagues

Personal intelligence (PI) involves the ability to recognize, reason, and use information about personality to understand oneself and other people. Employees in two studies (Ns = 394, 482) completed the Test of Personal Intelligence (TOPI; e.g., Mayer, Panter, & Caruso, 2017a) and assessments of workplace perception and behavior. Higher PI was associated with higher perceived workplace support and lower counterproductive work behavior. These relationships continued to hold after controlling for other key variables. The results indicate the TOPI, although still in research trials, shows promise as a screening device for selecting employees and targeting individuals for training

Trade in Small Arms and Light Weapons. Are embargoes effective?

This paper analyses the trade in Small Arms and Light Weapons (SALW) from 1990 to 2017. Our analysis relies on an unbalanced panel of 79,245 observations reporting SALW exports between 9,275 pairs of countries. In particular, we study the impact of embargoes on trade in SALW. We use a gravity model framework including, in addition to traditional gravity variables, specifically SALW trade controls. The main results show that: (i) embargoes reduce SALW exports to sanctioned countries by 33%; (ii) An EU embargo appears to determine a decrease of 37% of SALW transfers whereas for UN embargoes the impact is not significant. In addition, we found no warning signals of sanctions-busting. First, countries do not seem to import a larger number of SALW if neighbors are under an embargo. Secondly, the findings show that embargoes have no statistically significant effect on the trade in sporting arms. Results are robust to some robustness checks, in particular to endogeneity

A General Mathematical Formulation for the Determination of Differential Leakage Factors in Electrical Machines with Symmetrical and Asymmetrical Full or Dead-Coil Multiphase Windings

This paper presents a simple and general mathematical formulation for the determination of the differential leakage factor for both symmetrical and asymmetrical full and dead-coil windings of electrical machines. The method can be applied to all multiphase windings and considers Görges polygons in conjunction with masses geometry in order to find an easy and affordable way to compute the differential leakage factor, avoiding the adoption of traditional methods that refer to the Ossanna's infinite series, which has to be obviously truncated under the bound of a predetermined accuracy. Moreover, the method described in this paper allows the easy determination of both the minimum and maximum values of the differential leakage factor, as well as its average value and the time trend. The proposed method, which does not require infinite series, is validated by means of several examples in order to practically demonstrate the effectiveness and the easiness of application of this procedure

Gapped Surface States in a Strong-Topological-Semimetal

A three-dimensional strong-topological-insulator or -semimetal hosts topological surface states which are often said to be gapless so long as time-reversal symmetry is preserved. This narrative can be mistaken when surface state degeneracies occur away from time-reversal-invariant momenta. The mirror-invariance of the system then becomes essential in protecting the existence of a surface Fermi surface. Here we show that such a case exists in the strong-topological-semimetal Bi$_4$Se$_3$. Angle-resolved photoemission spectroscopy and \textit{ab initio} calculations reveal partial gapping of surface bands on the Bi$_2$Se$_3$-termination of Bi$_4$Se$_3$(111), where an 85 meV gap along $\bar{\Gamma}\bar{K}$ closes to zero toward the mirror-invariant $\bar{\Gamma}\bar{M}$ azimuth. The gap opening is attributed to an interband spin-orbit interaction that mixes states of opposite spin-helicity.Comment: 5 pages, 3 figure
